Holder, of which the following is a specification.

ldental disk holder, in which a multiple number of disks of varyingsizes and kinds may be mounted on a multiple number of posts, eitherspring or rigid, as desired, fastened to or mounted on a supportingplate and arbor which is sustained and maybe revolved on a verticalshaft supported by a substantial base; and the objects of my inventionare; first, to provide a universal and compact holder for storing andretaining a multiple number and kind of disks; second, Va convenientholder which may be placed and adjusted to the will and convenience ofthe operator; third, to lock the disk in place at the will of theoperator, as in case of accidental upsetting or other inconvenience,that they'may not be displaced. T attain these objects by the mechanismillustrated in the accompanying drawings, in which,-

Figure 1, is a general perspective view. of machine, showing one post(4) disengaged so as to remove disks; .Fig 2, is a vertical sectionalview showing detail construction of the same.

Similar letters refer to similar 'parts throughout the several views.

1 is a supporting'base to which is fastened a vertical shaft 2. Thislbase and shaft may be in one or in separate pieces.

3 is a cylindrical block of wood, fiber, or other desirable material,with vertical grooves 4 on the outside surface, made toit and receivespring loops which receive and store disks 5, as seen in Fig. 1. A wideloot-l tom plate 6 is securedl by screws 10 to the lower end of the coreand is provided with radial slots 7 around its periphery, and a top'plate 8 is secured by screws 9 to the upper end of the core and overliesthe` up- -per ends of its' grooves 4 slightly. Said loops are preferablymade of spring mate- 'rial held in place in grooves on outside surfaceof and to core 3 by cylinder 11 which surrounds and is slightly shorterthan the core. Thus the shank of each loop is held removably in placebetween the two plates 6 and 8, its lower end is bent outward as at 12over the exposed dpart of the lower plate 6, carried downwar in a slot 7thereinv as seen at 13, and then carried upward throu h such slot 1n aspring tongue 14:; whereas t e 60 upper 'end of said shank isbentoutward as at 1 2 into an arm 15 Which has a hook 16 at 1ts outerextremity adapted to engage sald tongue.' The normal position ofthelatter isabout that shown .at the left of Fig. 1, or in other 'wordswhen disengaged from the hook it springs outward so that the disks 5 orother articles stored thereon may be lifted olf the tongue with ease;but at other tunes the, tongue is borne inward and en- 7e gaged with thehook 16 as seen in Fig. 2 so'A that whatever is mounted on the tonguemay not be dislodged therefrom, even if the entire device should beaccidentally knocked over. .The depressed portion '13 of each 75 loopserves two functions. First it gives resiliency to the loop between itstongue 14 and the remaining portionl thereof, so that the tongue itselfreally does not have to bend much if any, and yet this resiliency isbelow the line ofthe bottom plate 6 so that it does not detract fromthelength of the tongue and the capability thereof for storage. Second theengagement of the de-v pressed portion 13 with the slot 7 prevents 85the swinging of the loop from side to side which otherwise might' occurbecause its upright shank is mounted in one of the grooves 4. It will beobvious that in order to serve these two functions it is not essen- 9 0tial that the depressed portion 13 be given exactly the configuration'shown in the drawings, so long as it is a bend or perhaps even a coil ofthewireof which the loop yis composed, and it projects through the slot7 and 95 stands mainly .beneath the line of the plate 6. At 8 shaft 2 isreduced in size fromv the main body so as to form a shoulder to isupport plate 8 and allow the holder or container to revolve thereon.,This shoulder may be on the lower end so as to'support plate 6 asvdesired or at any other desired point or by any known convenient method;17 is a nut threaded and screwed to the upper end of shaft 2 to hold orlock the holder 105 or container in place. Having thus 4described theinvention, what is claimed is:

1. In a device of the class described, the combination with a coresupported on an upright axis, and a plate securedacross its lower endand projecting beyond its face and provided with radial slots in itsperiphery; of a series of loops whereof each has an upright shanksecured tov said core, anv

outwardly projecting arm at the upper end of the shank provided with ahook at its extremity, the lower end of the shank being bent outwardover said plate and then depressed through one of said slots, and atongue rising from the depressed portion and removably engaged with saidhook.

2. ln a device of the' class described, the comloination with an.Upright support, a core rotatablymounted thereon and having uprightgrooves in its surface, anda plate secured to the lower end of the coreand projecting beyond said surface, the plate having radial openings inits projecting portion; of a series of. loops whereof each has astraight upright shank mounted in one of said grooves, an outturned andhookedarm at its upper end, and its lower end bent outward over theplate, depressed into one of said openings therein, and then broughtupineone a. a a ward agaln 1n sald opening lnto a spring -theextremities ofsaid grooves, one of the plates having openings alinedwith the grooves, and a .cylinder surrounding said core and its groovesand shorter than the core so that the ends of the grooves adja- ,centthe plates are left open; of a series of loops whereof each has a shanklying in one groove, ends bent over the edges of the surroundingcylinder-and one of them engaging one of said openings, and a hook onone end and a spring tongue on the other, for the purposeset forth.
